WINDMILL Specification of letters Patent.

Patented Mar. 11, 19.19.

Application filed October 22,1917. Serial No. 197,952.

To` all-whom' t may concern:

Be it known that I, WILLIAM C. BROWN- ELL, a citizen of the UnitedStates, residing at. Pueblo, in the county of Pueblo and State `ofColorado, have invented certain new and vruseful Improvements inWindmills, of

whichl the following is `a specification.

This invention relates to wind mills, and

its primary object resides in the provision of a wind--actuatedmechanism whose driving power is increased by the peculiar arrangementof a plurality of vane-wheels which cooperate to furnish motive power toa driven shaft. l

A' further objectof the invention resides in the provision of anautomatic governor for regulating the movement of thewind- 'wheelsund'er varying wind :pressures to maintain lthe driven-shaft at asubstantially uniform rate of speed. y

Still other objects of. the invention relate to details of construction'and arrangement of parts, allv of which will fully appear in the courseof the following description.

illustrate an embodiment of my invention and in which similar charactersof reference designate corresponding parts in the several views, i

Figure 1 is a plan view of the operating mechanism of my improvedwind-mill, in its preferred form,

Fig. 2, a section taken along the line 2 2,

' Fig.l 1, and

Fig. 3, a section along the line 3--3, F ig. 2. i

Referring to the drawings, 2 designates a ysuitably supported platformupon which is mounted a base 3 for the support of the voperating partsof the wind-motor.

The base provides a step-bearing for a rotary standard 4f which has atits upper end, two axially. alined boxes 5 for the support of thedriving shaft 6 of the motor.

The shaft carries at its opposite ends, the front and rear wind-wheels 7and 8 the vanos of which are pitched in the same direction to impart arotary motion to the shaft by action of the wind.

The driving shaft carries a beveled gearwheel 9 which transmits itsrotary motion to a corresponding wheel 10 at the upper end of an uprightshaft 12 extending through alined bores in the standard 4 and the base3' and supported for rotation upon a suitable bearlng 13.

Ymitted fby means In the accompanyingdrawings which' The movement oft-hedriven shaft is transof a pair of beveled gearwheels 14 and l5 to acrank-shaft 16 set at right angles thereto, for the operation of a pumpor other mechanical device, through the medium of a pitman 17.`

An auxiliary wind-wheel 18 the vanes of which are pitched reversely withrespect to those. of the Wheels 7 and 8 at the ends of the drivingshaft, is mounted for independent rotation in one of the bearings of thestandard 4 by means of a 'tubular hub 19 through which the shaft 6loosely extends. i

The hub carries a beveled gearwheel 20 which meshes with thebefore-mentioned gear-wheel 10 at the end of the driven shaft,.

opposite to that at mally extends in parallel relation to the y drivingshaft, or at right angles to the piarallel planes of rotation of theVwind wheels.

The rudder is fastened at the end of a 'shank or stem 22 provided with acollar 23 for its rotary support upon a iange 24 at the lower end of thestandard 4, ing a counterbalancingweight l25.

i governing rudder 26 of smaller area is mounted at the end of a shank27 in rigid connection with the rotary standard, as best shown in Fig. 3of the drawings, and eX- tends at right angles to the primary rudder 21with which it is connected by means of a leaf-spring 28.

This spring is at its ends att-ached to the.

and carry- In the operation of my improved windmotor, the primary rudder21 normally maintains. the wind-wheels in the proper position to facethe wind'and thereby furnish the motive power required for the rotationof the driven shaft.

The wind after acting on the front wheel 7 18 for its rotation in .theopposite direction after which it engages the rear wheel '8 which isturned in the same direction as the first-mentioned wheel.

Since the gears on the. shaft and the hub of the auxiliary wheel actupon the` gearwheel on the driven shaft at opposite points, the rotarymovements of the three vanei do ' tion te the aircurrents, and theoperating on said driving shaft in mesh vvit n ially in the direction ofthe `vvind, the

the Wind.

wheels are combined to impart a, rotary niotion to the drive-n shaftwith a poiver greater than that obtained either a single wheel or bytivo uieels the vanes of which are pitched either in the same. or inopposite directions.

Since the primary rudder extends norgoverning; rudder, beinggY ofsmaller area, is nnder the saine eonditions kept in facingrelaparts ofthe motor are thus under normal conditions held constantly in the properpd sition relative 'to the direction of the vrind.

Vl/Vhen, hoivever, the force of the ivnd increases beyond a certainpredeterminedliinit established by the resistance of the spring, 28, itsaction upon the governing blade Will cause the spring to yield, With theresult that the standard is inovedabont its axis and the vane Wheelssupported thereon are turned to face at an angle to thedirection of Themotive power of the Wheels is thus automatically controlled inaccordance with Wind'variations to efleot the rotation of the driven.shaftr at a substantially uniform rate of speed. j

l desire it understood that. While l have described and shown theembodiment of my invention which at present appears simplest and bestadapted for its purpose, such mi- `nor changes in 'the details ofconstruction and arrangement of the operating', transmis- 'sion andcontrollingmechanisms of my inn proved Windmill may be resorted to asare Within the scope of the followingg` claims.

I Claim:

l. ln a Wind mill, aV driving shaft, ivind Wheels affixed to the. endsof said shaft, a driven shaft disposed at. right angles to the drivingshaft inwardly froin the ends of the latter, a gear on said drivenshaft, rear h the said driven shaft gear, anauxiliary Wind wheel on saiddriving' shaft and rotatable independently of the latter, and a gearcarried by said auxiliary ivind ivlieel and in niesh with the saiddriven shaft gear.
